Set correct volume storage path for SDK sandbox

Context.getDataDir() for SDK sandbox incorrectly returns /data volume
path even if the actual storage is on another volume. This CL sets the
correct storage path by checking the uuid from the ApplicationInfo of
the client app and setting it to the same value.
